Abstract
A method of film production includes the steps of obtaining defect information including information on the position of a defect (D) in a separator original sheet (), slitting the separator original sheet () to produce a plurality of separators (), and determining, on the basis of the defect information on a single defect (D), that a separator () actually having the defect (D) and another separator () adjacent to the above separator () are defective.
